The aim of this module is to continue the introduction and analysis of the principles of operation of electronic devices and circuits using the principles introduced in ôAnalogue Electronics 1ö. A more in-depth analysis will be undertaken using suitable analysis techniques. At the end of this module students should be able to solve problems concerning simple DC circuit theorems and analyse AC circuits using both the phasor approach and the complex notation approach.

SINUSOIDAL SIGNALS: Single phase generation by coil rotating in magnetic field. Trigonometric representation, amplitude, frequency and phase concepts. Voltage and current relationships for resistor, inductor and capacitor. Reactance. Response of R-C, R-L and L-C circuits to sinusoidal signals. Impedance. Phasor diagrams. Power topics; distinction between power and VA, power factor. COMPLEX ANALYSIS: Analysis of circuits using complex notation, derivation of amplitude and phase data from complex representation of signals and impedance. Transfer functions, frequency response, corner frequency, Bode diagrams for simple R-C circuits. Power dissipation in complex impedance. Maximum power transfer theorem for complex source and load impedances. TUNED CIRCUITS: Series and parallel R-L-C circuits, resonance, Q, bandwidth, dynamic impedance. Circulating current in parallel tuned circuit. COUPLED CIRCUITS: Inductively coupled coils, induced e.m.f., mutual inductance, coupling coefficient. Reflected impedance for loaded coupled circuit for k < 1. Input and output equivalent circuits. Properties of ideal voltage and current transformers. The auto transformer.
